Title: Adaptive equalizer circuit
Inventor: NISHIMURA KOUICHIROU
IPC: H04B3/06
Filed: 2001-03-13
Granted: 2002-08-11
Abstract: In an adaptive equalizer circuit, to an input having a fluctuating amplitude, a stable adaptive equalization operation can be realized without changing over a reference value for computing an equalization error. An input signal is held as a sample with a timing signal shifted from a reference clock of the input signal by a phase of 1/2 cycle. An equalization output is computed from an obtained sample data. The difference between only the first output value after a zero-crossing and an arbitrary set reference value is computed and the computed value is set as an equalization error. A coefficient of the adaptive equalization circuit is updated from the equalization error and the sample data. Further, to the displacement of the symmetry of the input signal, the reference value of the adaptive equalizer circuit is changed corresponding to the change of a binarization threshold value of a binarization circuit which constitutes a rear stage of the adaptive equalizer circuit.

Title: Pre-metered dose magazine for breath-actuated dry powder inhaler
Inventor: KEANE LAWRENCE
IPC: A61M15/00
Filed: 2001-06-22
Granted: 2004-12-01
Abstract: A pre-metered dose assembly for consistently supplying precise doses of medicament is provided for a breath-actuated dry powder inhaler. The assembly includes a cap defining a dry powder delivery passageway for providing air to a dry powder supply port of a swirl chamber of a breath-actuated dry powder inhaler, and a magazine including a plurality of reservoirs for holding pre-metered doses of dry powder. One of the magazine and the cap is movable with respect to the other of the magazine and the cap for sequentially positioning the reservoirs within the delivery passageway of the cap. A breath-induced low pressure at an outlet port of the swirl chamber of the inhaler causes an air flow through the dry powder delivery passageway of the assembly and into the dry powder supply port of the swirl chamber that entrains dry powder from the reservoir positioned in the passageway for inhalation by a patient using the inhaler. The present disclosure also provides a breath-actuated dry powder inhaler including the pre-metered dose assembly in combination with a de-agglomerator for breaking up aggregates and micronizing particles of dry powder prior to inhalation of the powder by a patient.

Title: Variable pitch lead screw based steering mechanism
Inventor: SHYU JENG-HUEY
IPC: B62D5/24
Filed: 2001-07-19
Granted: 2002-06-11
Abstract: The present invention relates to a variable pitch lead screw based steering mechanism comprising a steering shaft to which a primary bevel gear is mounted, a left side secondary bevel gear and a right side secondary bevel gear mating the primary bevel gear and respectively driving a double-threaded left side variable pitch lead screw and a double-threaded right side variable pitch lead screw, a left side follower member and a right side follower member mating the variable pitch lead screws and movable thereby, an upper casing and a lower casing encasing the variable pitch lead screws. Operating a steering wheel causes rotation of the steering shaft which is transmitted into rotation of the variable pitch lead screws. The variable pitch lead screws induces movement of the associated follower members to move drag links for driving steering knuckle arms which in turn drives the front wheels to turn. The present invention takes advantage of the non-uniform transmission of the variable pitch lead screws to make turning angle of the front wheels completely follow the Ackerman Principle. That is the extended lines of three rotation axes of two front wheels and two rear wheels precisely intersect at the same point when the vehicle turns.

Abstract: In a system for storing and displaying images, such as in a personal computer or mobile telephone, a display apparatus is provided which selectively displays virtual reflections of the real environment according to mirror values encoded with the stored image. A camera (302) provides real-time environmental image data which, under control of the CPU (100), are stored in memory (106, VRAM3). For transparency effects, background image data (RGB2) are mixed (110) with the foreground image (RGB1) under control of a transparency code (T). The resultant pixel values (RGB3) are further mixed with the environmental image data read out of VRAM3 which are left-right reversed (118) to simulate a true mirror image) for output to the display device (300). The image from another camera (310) can be used in the same manner to provide a virtual transparency function. By controlling the transparency and reflection effects for each pixel of the image, various special effects and a more realistic display can be achieved.

Filed: 2002-05-24
Granted: 2004-02-11
Abstract: In a telecommunications network, for establishing or modifying a radio connection a node (N<SUB>1</SUB>) prepares and sends an AAL2 signaling message ( 110 ) for use by a connection admission control function ( 106 ) of another node (N<SUB>2</SUB>) of the telecommunications network.
